Hello, Elle,
Yes, you can get a personalised crossword.
It is a good idea, especially for a crossword nut!
Type "Custom cryptic crosswords" into your Google and it will all be revealed. The two named setters are Boatman and Enigmatist of the Guardian, plus unnamed setters.

And they need a good bit of notice.
Well, I would not be good at knowing different cakes, d'ye see?
Untalented in that field!
Cupcake is a new word to me, and that is OK.
I like exploring the language.
Fairycakes sound familiar, though.
